VS 2015

For a new release to support VS 2015, does anyone have opinions on whether we should continue to publish a single MSI installer for multiple versions of Visual Studio, or should we do a standalone installer for VS 2015? I think that it is much more common
these days for teams to be on the latest version of Visual Studio, so a new version of NuPattern that supports VS 2015 only might make more sense now than it used to. Thoughts?
